TMCNET eNEWSLETTER SIGNUP

Patterson Companies, Inc. (Nasdaq: PDCO) today announced that the
Federal Trade Commission (FTC (News - Alert)) has issued an administrative complaint
against Patterson alleging an agreement with its competitors not to sell
to "buying groups" in violation of federal antitrust laws.

The Company believes that the allegations as described are meritless and
intends to defend itself vigorously. The complaint seeks injunctive
relief and does not seek monetary damages. The Company does not
anticipate that this matter will have a material adverse effect on our
financial condition or results of operations.

Patterson maintains the highest levels of integrity and ethical
standards and has a 140 year history of partnering with all types of
customers to grow their businesses and provide outstanding care to their
clients.

Patterson's
Animal Health segment is a leading distributor of products, services and
technologies to both the production and companion animal health markets
in North America and the U.K.
